To all whomiit may concern:

Beit known that I, CHARLES FRANCIS JENKINS, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements ceptacles; and I do hereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention vrelates yto bottom closures l for receptacles and has for its object the production of a closure of this nature which will be exceedingly chea to manufacture, and to put into place; an which, when once posil tioned. will be efficient in action.

To these ends the invention consists in theV novel details of construct-ion and the combination of parts more fully hereinafter disclosed, and particularly pointed out in the claims.

. larger Referring to the accompanying ,drawings forming a part of this specification in which like numerals refer to like parts'in all the views, Figure 1 is a longitudinal sectional` .view of a vessel showing a portion of the bottom closure in place and diagrammatically illustrating a means for placing the remaining portion of the closure in position; Fig. 2 is a sectional view of a vessell after the bottom closure is`in place; and' Figs. 3 4and 4' are detail sectional views illustrating features to be referred to hereinafter.

1 represents any suitablevessel body, preferably of acylindrical form; and 2 a lower half of the bottom closurev which, if the body 1 is circular in cross section, will'be in the .form of a disk. The portion 2, is shaped to fit the interior of the body 1,` is slightly than the same, and is dished as illustrated while being placed in the body. 3, in Fig. 1, illustrates the other portion of the closure which is likewise slightly larger than the interior of the vessel l; and 4 is an suitable means as a shaping die throug which the said portion `faimay be forced by the plunger 5 and dished as indicated in Fig. 2. l

t is preferred to place a small portion of glue 6, or other fastening means, upon the closure 2 before it is inserted into, the body 1 so that when the portion 3 is forced through the said body into the position shown in Fig. 2, the two portions 2 and 3 will be firmly held together. After the said portions 2 and 3 are in position as indicated they will efi'ectually resist motion in either direction for that their respective edges 7 and 8 will tend to bite into the walls of the body 1, and thereby tend to seat themselves more firmly than before. In Fig. 3 there is illustrated the effect of pressure from the inside of the body tending to' force the closure out-ward, and a bend 10 inthe portion 2 is of such a nature as to force the edge `8 outward and firmly against the inside of the body 1. In the samewa should pressure be. applied in the direction of the arrow shown in Fig. 4, the bend 11 would be formed in the portion 3 and the edge7 would staiitially as described.

2. In a vessel the combination of a'body likewise be forced firmly against the interior portion, and a closure comprising op ositely dished portions the extreme edges o which fit the interior of said body portion, and means for securing said portions together; .substantially as described.

3. In apaper vessel the combination of a body `portion, and a pair of oppositely dished disks closely fitting the interior of said body portion and glued together; substantially as described. l

In testimony whereof, I affix my signature, in presence of two witnesses.
